Dragon Ball Broly Dimension feat

So I was discussing this with some other but I wanted to see what people think about this feat. So during Broly's fight with Gogeta the two of them blast each other with enough power to send themselves into another dimension and then later the two clash with each other and shatter said dimension

Here's the light novel description

Energy containing the might of a different dimension collides between the two. A flash of light surges as a silent explosion expanded. The next instant, Gogeta and Broly found themselves within a dimension of swirling strange lights. The boundary of the dimension could not withstand the energy released by them and got torn apart

So I was wonder what people's thoughts on this feat were, and how they would quantify it. I have seen pretty varied opinions.

@thewatcherking: this is what’s important, because the animation when they escape back to earth is different than when they break into the dimension.

When ssj Gogeta and ssj Broly clash they obviously didn’t destroy the reality they live in, just the dimensional barrier. The clash that brought them back to earth looks more like the dimension that clashed in as SSB Gogeta and lssj Broly could have been destroyed.

The real question should be how much energy is enough to destroy dimensional barrier? And also how is their clash comparable to beerus vs goku? In BoG side effects of battle thretaned to destroy universe but in Broly movie they broke dimensional barrier and that is what i do not understand...

I don't think it is as impressive as some people seem to think it is. The Z Fighters and villains were able to break through dimensions during Fusion Saga (Buu Arc). Super Buu did and later SSJ3 Gotenks broke the dimensional barrier.

The only difference is that the Z Fighters are far more powerful and they should dimension bust more often but don't due to plot reasons or Akira Toriyama forgetting this ability.

This feat >>> any feat in DBZ. The feat of buu collapsing the universe is not even cannon. Also the feat of gotenks and buu ripping a hole in the dimension doesn't even compares to this since they shattered the dimension at the end of their clash. Shattering a dimension out side of the universe >>> ripping a little whole with vice shout.

Without the size of those dimensions we can't really say. And it's not like it's the first time dimensional stuff like that happened. Toei fell in love with those stuff after Toriyama first shown Buu/Gotenks yelling a dimensional portal, Vegeta destroyed RoSaT dimension twice, GT Goku destroyed dimension, whole deal with Buu crashing alternate dimensions, Goku and Jiren breaking Hit dimension, Anilaza warping space with his punches, Kale and Caulifa destroyed dimension of that chick pride trooper aswell. It happenns all the time but without concrete size those feats are pretty much useless (except as a BFR counter I guess).
